Method and system for using virtual tunnel end-point registration and virtual network identifiers to manage virtual extensible local area network access

摘要

A method and system for securing a VXLAN environment, including configuring a default network policy, associated with interfaces of the network device, for dropping all VXLAN frames including a VXLAN attribute; obtaining, by the network device, registered VTEP identifiers; determining, using the registered VTEP identifiers, that an interface of the network device is operatively connected to a registered VTEP associated with a registered VTEP identifier; disassociating the default network policy from the interface based on the determination; receiving, at the interface, a frame; performing a first verification that the frame is a VXLAN frame by examining the frame to determine that the frame includes the VXLAN attribute; performing a second verification to determine that the VXLAN frame includes a registered VTEP identifier; allowing, based on the first verification and the second verification, the network device to process the VXLAN frame; and processing the VXLAN frame.

1. A method for securing a virtual extensible local area network (VXLAN) environment, the method comprising:
configuring a default network policy on a network device for dropping all VXLAN frames comprising a VXLAN attribute, wherein the network policy is associated with a plurality of interfaces of the network device; obtaining, by the network device, a plurality of registered VXLAN tunnel endpoint (VTEP) identifiers; determining, using the plurality of registered VTEP identifiers, that a first interface of the plurality of interfaces of the network device is operatively connected to a first registered VTEP associated with a first registered VTEP identifier of the plurality of registered VTEP identifiers; disassociating the default network policy from the first interface based on the determination that the first interface is operatively connected to the first registered VTEP; receiving, at the first interface of the network device, a frame; performing a first verification that the frame is a first VXLAN frame by examining the frame to determine that the frame comprises the VXLAN attribute; performing a second verification to determine that the first VXLAN frame comprises a first registered VTEP identifier; allowing, based on the first verification and the second verification, the network device to process the first VXLAN frame; and processing, by the network device, the first VXLAN frame.
